CVE-2026-53208

The CVE-2026-53208 entry concerns the Linux kernel Bluetooth subsystem: BR/EDR signaling packets are not enforcing MTUsig, allowing a remote BR/EDR peer within radio range (before pairing) to send a single 681-byte signaling packet containing multiple L2CAP_ECHO_REQ commands, which can trigger 16...

CVE-2026-10639

In Zephyr's native IPv4 stack, icmpv4handleechorequest in subsys/net/ip/icmpv4.c builds an echo-reply packet reply, hands it to nettrysenddata, and then, on success, calls netstatsupdateicmpsentnetpktifacereply. nettrysenddata transfers ownership of reply to the TX path netiftryqueuetx - netiftx ...

An update is available for mtr. This update affects Rocky Linux 9. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list MTR combines the functionality of the 'traceroute' and 'ping' programs in a singl...

Disable the System from Responding to ICMP Broadcast Packets

Internet Control Message Protocol ICMP transmits query packets and error packets. You can configure a policy of not receiving ICMP broadcast packets to defend against ICMP packet attacks. This parameter determines whether a device needs to respond to the ICMP echo messages and timestamp requests...

CVE-2024-6640 pf incorrectly matches different ICMPv6 states in the state table

In ICMPv6 Neighbor Discovery ND, the ID is always 0. When pf is configured to allow ND and block incoming Echo Requests, a crafted Echo Request packet after a Neighbor Solicitation NS can trigger an Echo Reply. The packet has to come from the same host as the NS and have a zero as identifier to...

CVE-2024-6640

CVE-2024-6640 concerns FreeBSD pf: In ICMPv6 Neighbor Discovery, the ND state ID is always 0. When pf is configured to allow ND but block incoming Echo Requests, a crafted Echo Request after a Neighbor Solicitation from the same host with identifier 0 can trigger an Echo Reply, causing ICMPv6 pac...

SUSE CVE-2012-2394

Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 on the SPARC and Itanium platforms does not properly perform data alignment for a certain structure member, which allows remote attackers to cause a denial of service application crash via a 1 ICMP or 2 ICMPv6 Echo Request packet...
